[0116] Here, the blockout is a portion where concrete is not poured in the process of manufacturing a concrete panel and is also referred to as a core.
[0117] Also, in the case of the inner mold 120, a rack installation shear anchor, which is a shear anchor pre-embedded in the curved concrete panel 200, may be installed on the rack installation convex portion 120c.
[0118] Also, mortar, which is a bedding material, may be injected so that a bottom surface of the curved concrete panel 200 and a concrete base layer are integrated, and a bedding material inlet forming material may be installed on each of the left and right rail installation convex portions 120a and 120b to form the bedding material inlet. In particular, an impact-absorbing block is applied between several blocks as illustrated in

[0126] Also, as illustrated in
[0127] Meanwhile,
[0128] As illustrated in
[0129] In the case of the curve portion mold structure for manufacturing a curved concrete panel for a mountain railway rack track according to an embodiment of the present disclosure, an introduced pressure is adjusted for each position of the side screw jack 130 to implement the shape of a panel according to a curve while maintaining an inner width of the curved concrete panel 200.
[0130] Also, in order to implement a side slope of the curved concrete panel 200 according to a difference between an upper width and a lower width, an introduced pressure of each of an upper screw jack and a lower screw jack that correspond to sidewall molds 110b is adjusted. Accordingly, a pressure may be introduced according to a pressure difference for each position of a screw jack due to application of a plane curve and a pressure difference for implementing a sidewall slope.
